the. fraaie 18 having the hiking pad `19 and the printing face 20thereon. I do not show thcidetails of such inking pad or printing face.hut it will be. understood that suitable ink supplying devices areassociated with the pad to keep vthe hiking roiis 11, 11 pro erly inkedand the printing face willige adapted to receive the type or plate whichis to linpartV the impression. As the gear wheel 6 rotates with itsassociated cani plate 16, the two rods 9 and 17 will tend to rock i theframes l() and 1t; to and fro, but since the 'frame 10 is related asindicated to the arm 14 it Wiil swing on the axis 21, which axis is theline of pivotal connection between the frame 10 and the rods 9 and 17.Thus the inkingl rolls will travel batik and forth over the printing;lsurface and the inking pad. These parts are -very similar to those ofWell known types of printing maohines. A The ai'in 14, however, is bentdown for the `reason hereinafter set. forth.

Rising' from the upper part of the fraaie lv which carries the pin 23 onwhich the partsnow to he described are mounted. The irst of `these partsthe bag carryingl device consisting of the central plate 24 and arnisprojecting therefrom.

i One set of these arnis 25, 25 are adjustably seeured by means ofV theslots 2G, and the tliiunh screws 2T. Another-fart 28 are pivoted at Ztland their inner ends are forined inthe Shape of elbow crank levers 3()which overlap as indicated iii Fig. 5, and they are `Hmiiibly drawntogether by the spring 31.

Each ypair of adjacent arnis 25 and E28 torni .is hereinat'terexplained. the bag nia'vbe reversed or turned on this ling' holdingdevice so that it lieeonies also a bag turning device.

.t modification of this strurture is shown in Figs. S and 9 where, foreai'li of the arms 35, I'substitute a broad platen 32 which is securedadjustahlv in like manner by the slot Qt and iliiinib screw 2i'. $3 is alingy shown in position on thi` han lifoldor iii several oi thefigures.y The platen last described is esperiall)v useful where the bagsare to he tprinted on both sides and thc structure for doin;r that isdiag annnatically illustrated iu Fig. 7, where a duplicate of theprinting de- Vvice, which,` taken as a whole, is mounted on Aframe 18,is shown yas 'mounted on frame 3l. course, the connections and drivingparts would, in the. case of the use of two printing plate 24. As therod 39 descends, the rodv devices, re uire to be changed from that shownin t e drawings, but such chan es would readily occur to any mechanic.ll that is necessary for my purpose is to indicate that two suchprinting devices might be employed, one to print on one side and theother to print on the other side of the bag simultaneously. Details ofYstructure which am here illustrating relate only to the operation of oneprintin device and the simultaneous and relate operation of the baghandling device. Returning now to the bag holding devices and referringto those illustrated at the top of the drawing, it will be found thattwo holders of a iven pair are inclined toward each other an that thebag can, therefore, be easily slipped onto its holder where it hangs inthe loose position as indicated in Fig. 2. To stretch the bag it is onlynecessary to moveone holder of each pair away from the other and thisoccurs when the spring 31 is left free to act as is the case at the leftof Fig. 5 and the right of Fig. 2. Y

Assuming now that the machine is in the position shown in Fig. 2 withcertain' stretched bags in position and other loose bags in position, itis necessary in order to brinU the stretched bags down where they can eprinted to turn the bag carrying device in the direction indicated bythe arrow in Fig. 2. This is done bythe following mechanism: 35 is' anarm pivoted on the frame at 36 and held in the position shown in Fig. 1by the spring 37 against the stop 38 on the frame l. Pivoted to this armis the rod 39 which is connected to the elbow crank lever 40 which ispivoted to the support 22 and is pivotally connected at the end of itsother branch-to the rod41 which is pivoted to the arm 42 on the collar'43, mounted on the sleeve 44, which is pivotally mounted on the pin 23.On the same sleeve 44 is secured the plate 24 which carries the bagholding devices. This is the part which must be turned to bring thestretched bag's into position for printing. Y When, in the course of theoperation o the machine the arm 35 is engaged by -the pin 45 on theframe 10 as' indicated in Fig. 1, the further motion ofthe machine willbring the arm 35 to the position shown in dotted ines in Fig. l and thiswill draw down on the rod 39, rock the elbow crank lever 40 and turn thecollar 43. The pin in the outer portion of the arm 42 is adapted to engae the recess preferably shaped as indicate in dotted ines in Figi 4, inthe dog 46 which is pivoted y at 47 on the support 22 and inwardly drawnby the spring 48. Its end, therefore, lies between` i e ends of two ofthe four cams 49, 49. A second do 50 is pivoted on the arm 42 and isadapte `to engage one of four projections 51 on the hubassociated withthe 41 isdrawn to the ri ht as indicated in Fig. 4, thus first forcing tle dog 46 backward and out of engagement with the cam 49 and thenbringin the dog 50 into en agement with the projection 51 whereby t eplate 24 is rotated and the parte are so adjusted that it will travelninety degrees and bring the next set of stretched bags down between orinto roper relation to the printinl mechanism.

ere the ba s will be printe by the continuance of t e operation eitheron one side or both sides, b'y the assistance of the double printingdevice when emplo ed, and the as- .sistance of the wide inner p aten ofFigs. 7,

8 and 9 when that'is employed. As soon as the bags are thus printed theyshould be ,released or discharged and this will be accomplished bybringing the stretching arms and platen quickly together. This isaccomplished by the mechanism which I shall now describe.

Assuming that the bag stretching or holding devices are in the positionindicated in Fig. 5, and having reference to those at the lower part ofthe drawing where they may be supposed to hold a'bag which has just beenprinted on .one or both sides, the object is to uickly release thesebags so that they ina all o" before the upper rotation of their holdersbegins.` This will be done by bringing the cam 59 quickly around in thedirection indicated by the arrow in Fig. 5 against the, upper ends ofthe elbow crank levers 30 whereby the stretched and -the bag ho dingarms 28, 28 will be thrown toward their associated ba holding arms. Thetension on the bag wi be released and the ba discharged..

The cam is moved by the following means. Pivotally mounted on. a.bracket on the frame or .fixed partl of the machine is the bar 60 theend of which lies in the path way of the cam 8. To it isy ivoted the rodspring 31 will be i 61, the up er end of whic is' ivoted to one end oone branch of the el ow crank Ilever 62 which is while the other en ofthe elbow crank lever is pivoted to the rod 63', the other endv of whichis pivoted to thefprojection 64 on the collar 65. To this projection 64is secured the spiral spring 66, the other end of which is fastened to te support 22 b aI pin 100. Now, the collar 65 1s fastene by the setscrew 67 to the sleeve 44, to the other end of which is permanentlysecured the cam` 59.` The arts are so related that when the stretched as have been printed, the cam 8 engages. t e lower. end of the arm' 60,raises it, moves the sever'al parts until the cam 591s quickly drawnaround in the direction indicate by the arrow in Fi 5, and de resses thelower ends of the e bow crank evers '30, thus releasing the bags by asudden or jarrin motion so that they are quickly discharge from theirholders. Al-

ivoted on the frame 22,

most simultaneously with this action the operation of lifting the dogrlout of engagement is erformed. he arts are moved forwar another quartero therotation whereby the dogr 46 drops in between two of the cams 49and the parts are again locked in position. d

The use andV operation of my invention are as follows: The bags are putupon the bag holders as these rise to the top of the machine, and if thebags are to be reversed this can he done in the usual wa by drawing themdowuover the bag ho ding arms.

The action of the ap aratns then starts machinery forward anV the bagson the `arms are turned down toward the ri ht where it so desired andthe construction e as shown,

, the will be stretched. In any \event, they wil be carried downward.They will then,-

by the nea-t ste i, be carried to the 'lower T vpart of the mac inewhere they will be in` position to be printed on one or both sides andon the bags stretched or otherwiseand on the inner platen1if that beused. The 22S next forward step of the apparatus throws the rintecl bagsoit` and so the operation f continues. This apparatus furnishes meansfor.turning the. bags, for holding them, for feeding them to the press,for printing them and dischargin them and it requires no higher grade laor than what is necessary to turn the bags or run them` on the turningrarms. The character of the apparatus may ybe better'understood when Iexplain a little further the subject to which it relates. Bags may be`printed in the roller before they are nitide, but this involvesnumerous ditlicnltiesV The not here necessary to be discussed. completedbags may be printed'on ordinar V40` printing presses but this involvesgreat di eulties as will be seen at a lance. The prevailing raetice isto'pnint he bag blank on afeylin erpress andthen make up the bag.

Now when this is done, it is obvious that4 the- 45, manufacturer mustcarry in stock a quantity of printed bags'or the user must Ykeep a largestock in advance or there will be con 'siderable dela intllling anorder, because thefba'g lia'sftb e made from the blank which'isfjrstprnted Moreover, in this method expenslve help is required tooperate the 'cy inder press and expensiveplant is necest 'saiy andtheuser cannot well print his own y bags. By my system and apparatus the5,5 b is printed while it is carried by the ho der on the arms of whichit has been y turned. Thos the manufacturer, dealer, or user-may have aquantity of blank bags and when culled on to print for a certain specialAi order he has only to run them through thev printing press, associatedwith the bag turning device and the' work is done. Thus I vobviate delayand the carryin of stock.` By stretching the bags or sprea lng' themover66 the inner platen, the printiniz is most effectually and accuratelydone and the bn js can be printed on both sides, especial v where theinner platen is used.
